GERMANY DISINFECTANT, ANTISEPTIC, AND MEDICAMENT No Drawing. Original application filed January 2, 1925, Serial No. 274, and in Germany January 28, 1924.. Divided and this application filed June 26, 1926. Serial No. 118,843.

This invention is based on the recognition of the fact that thiocyanates, for instance potassium thiocyanate, which by themselves have only a slightly disinfecting action, are capable of considerably increasing the disinfectant, antiseptic and medicinal properties of heavy metal compounds, such as mercury, silver and the like, more particularly when the disinfectants or antiseptics are used in the presence of albumins, mucus, pus and the like.

For obtaining a disinfectant in accordance with the invention, potassium silver cyanide may for instancebe brought intosolution with suitable quantities of thiocyanate, barium thiocyanate or other thiocyanates. As potassium silver cyanide qvith potassium thiocyanate and the like in solution is con-. verted to complex salts, an excess of thiocyanate must be used, i. e. it must be used in quantities exceeding those required for formling complex silver thlocyanogen compounds.

For the manufacture of the products the primary substances may be introduced in solution, as described. Or mixtures may first be made of the primary substances to be used, such as potassium silver cyanide and potassium thiocyanate, containing the onstituents in suitable quantities, and these mixtures converted into the particular forms required. such as solutions, suspensions, salves, pastes,

sticks. The components may also be used one .after another, for intance by rubbing up one of them with a salve as a base and then adding the others. Finally several heavy metal salts maybe combined and the mixture activated by means of thiocyanogen compounds,

or a plurality of thiocyanogen compounds may be combined with one or more heavy metal salts. lln the disinfectants or medicaments, which may be made according to the as saponine and other substances having the property of reducing the surface tension, for

instance dextrin, starchand the-like. Activating thiocyanogen compounds are those of the alkalis, including ammonium, and of the alkaline earths, including magnesium.

Example that they develop only a very slight irritant action, so that they are eminently suitable for instance for use 1n forms, 1n which they come in contact with mucous'membranes.

This application is a division of my copending application Ser. No. 274 filed January 2, 1925, and now Patent No. 1,606,359.

What we claim is: p l. A disinfectant antiseptic and medicament comprising the combination of a'silver salt having a disinfecting action, and a light metal thiocyanogen" compound.

2. A disinfectant antiseptic and medicament comprising the combination of a silver salt having a dlsmfectmg action and an alkali thiocyanate. V 3. A disinfectant antiseptic and medicament comprising the combination of silver potassium cyanide and alkali thiocyanate.

In testimony whereof we have signed our names to this specification.
